You can choose how you install, configure, and administer the Sun Cluster software from several user interfaces. You can accomplish system administration tasks either through the Sun Cluster Manager graphical user interface (GUI) or through the command-line interface. On top of the command-line interface are some utilities, such as scinstall and clsetup, to simplify selected installation and configuration tasks. The Sun Cluster software also has a module that runs as part of Sun Management Center that provides a GUI to particular cluster tasks. This module is available for use in only SPARC based clusters. Refer to Administration Tools in Sun Cluster System Administration Guide for Solaris OS for complete descriptions of the administrative interfaces.
